Sad

So my minecraft instantly crashes when opening/creating world on singleplayer. I´m using MC 1.7.2 and I tried with Latest and Recomended forge versions. The only mod that I´m using is LegacyJavaFixer because if I don´t use it my game will not open. This is one of the crash reports: --- Minecraft Crash Report ---- // Sorry Time: 02/02/18 19:16 Description: Starting integrated server java.lang.NoClassDefFoundError: com/mojang/authlib/yggdrasil/YggdrasilAuthenticationService at net.minecraft.server.MinecraftServer.<init>(MinecraftServer.java:143) at net.minecraft.server.integrated.IntegratedServer.<init>(IntegratedServer.java:45) at net.minecraft.client.Minecraft.func_71371_a(Minecraft.java:2041) at cpw.mods.fml.client.FMLClientHandler.tryLoadExistingWorld(FMLClientHandler.java:669) at net.minecraft.client.gui.GuiSelectWorld.func_146615_e(GuiSelectWorld.java:183) at net.minecraft.client.gui.GuiSelectWorld$List.func_148144_a(GuiSelectWorld.java:257) at net.minecraft.client.gui.GuiSlot.func_148128_a(GuiSlot.java:209) at net.minecraft.client.gui.GuiSelectWorld.func_73863_a(GuiSelectWorld.java:216) at net.minecraft.client.renderer.EntityRenderer.func_78480_b(EntityRenderer.java:1061) at net.minecraft.client.Minecraft.func_71411_J(Minecraft.java:944) at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:835) at net.minecraft.client.main.Main.main(SourceFile:103) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:134) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at kml.game.GameStarter.main(GameStarter.java:46) Caused by: java.lang.ClassNotFoundException: com.mojang.authlib.yggdrasil.YggdrasilAuthenticationService at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:188) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 23 more Caused by: java.lang.IllegalArgumentException at org.objectweb.asm.ClassReader.<init>(Unknown Source) at org.objectweb.asm.ClassReader.<init>(Unknown Source) at cpw.mods.fml.common.asm.transformers.deobf.FMLDeobfuscatingRemapper.findAndMergeSuperMaps(FMLDeobfuscatingRemapper.java:347) at cpw.mods.fml.common.asm.transformers.deobf.FMLDeobfuscatingRemapper.getMethodMap(FMLDeobfuscatingRemapper.java:324) at cpw.mods.fml.common.asm.transformers.deobf.FMLDeobfuscatingRemapper.mapMethodName(FMLDeobfuscatingRemapper.java:297) at org.objectweb.asm.commons.RemappingMethodAdapter.visitMethodInsn(Unknown Source) at org.objectweb.asm.ClassReader.a(Unknown Source) at org.objectweb.asm.ClassReader.b(Unknown Source) at org.objectweb.asm.ClassReader.accept(Unknown Source) at org.objectweb.asm.ClassReader.accept(Unknown Source) at cpw.mods.fml.common.asm.transformers.DeobfuscationTransformer.transform(DeobfuscationTransformer.java:37) at net.minecraft.launchwrapper.LaunchClassLoader.runTransformers(LaunchClassLoader.java:276) at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:174) ... 25 more A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- Head -- Stacktrace: at net.minecraft.server.MinecraftServer.<init>(MinecraftServer.java:143) at net.minecraft.server.integrated.IntegratedServer.<init>(IntegratedServer.java:45) -- Starting integrated server -- Details: Level ID: Alv Level Name: Alv Stacktrace: at net.minecraft.client.Minecraft.func_71371_a(Minecraft.java:2041) at cpw.mods.fml.client.FMLClientHandler.tryLoadExistingWorld(FMLClientHandler.java:669) at net.minecraft.client.gui.GuiSelectWorld.func_146615_e(GuiSelectWorld.java:183) at net.minecraft.client.gui.GuiSelectWorld$List.func_148144_a(GuiSelectWorld.java:257) at net.minecraft.client.gui.GuiSlot.func_148128_a(GuiSlot.java:209) at net.minecraft.client.gui.GuiSelectWorld.func_73863_a(GuiSelectWorld.java:216) -- Screen render details -- Details: Screen name: net.minecraft.client.gui.GuiMainMenu Mouse location: Scaled: (184, 155).
